Having leim # dependencies in ../src as well would create a parallel race condition. # # 2) Files that are marked no-update-autoloads still get recorded in loaddefs. # So those files should be generated before we make autoloads, if we # don't want a successive make autoloads to change the output file. # Said changes are trivial (only comments in the "files without autoloads" # section), but still can be annoying. Of course, if generated lisp files # do contain autoloads, it is essential they be built before make autoloads. # (Also, if a generated file is not written atomically, it is possible that # in a parallel build, make autoloads could read a partial version of it.) # # We'd really like to add "make -C ../admin/unidata all" to gen-lisp # because of 2) above, but it causes a race condition in parallel # builds because ../src also runs that rule. Given the limitations of # recursive make, the only way to fix that would be to remove unidata # from ../src rules, but that doesn't seem possible due to the various # non-trivial dependencies. # We make $(lisp)/loaddefs.el a dependency of .PHONY to cause Make to # ignore its time stamp. That's because the real dependencies of # loaddefs.el aren't known to Make, they are implemented in # batch-update-autoloads, which only updates the autoloads whose # sources have changed. # Use expand-file-name rather than $abs_scrdir so that Emacs does not # get confused when it compares file-names for equality. autoloads .PHONY: $(lisp)/loaddefs.el $(lisp)/loaddefs.el: gen-lisp $(LOADDEFS) @echo Directories for loaddefs: ${SUBDIRS_ALMOST} $(AM_V_GEN)$(emacs) -l autoload \ --eval '(setq autoload-ensure-writable t)' \ --eval '(setq autoload-builtin-package-versions t)' \ --eval '(setq generated-autoload-file (expand-file-name (unmsys--file-name "$@")))' \ -f batch-update-autoloads ${SUBDIRS_ALMOST} # autoloads only runs when loaddefs.el is nonexistent, although it # generates a number of different files.
